Do cheap dual 8’florecent strip fixtures work better than 2 cheap dual 4’ strip fixtures? How are either for light output, lamp life, and overall economy?
I used 8' fixture with 4' bulbs. It was purely out of convenience. The 8' fixture was slightly less money than two 4' fixtures. A little less blocking to cut and nail between the trusses. A few less wires to worry about and half the ballasts (not a major consideration). I had 17 (actually need 1 more) to wire up so the thought of not doing 36 was pretty appealing. Rows are 9' apart and spaced 16" to 24" off the walls and 32" between fixtures. The light is fine.

Agree 100% as well as the 4' lamps are often on sale vs the 8' never seem to be nearly as discounted. If I was starting from scratch I would look at T5 fixtures as they are the brightest and most energy efficient common florescent out there at the moment.I recommend you consider a fixture that takes a 4' bulb. It's much easier to manage a 4' bulb than an 8' bulb. That goes for transporting the replacement bulbs, installing them and disposing of them.

I used 8' fixtures with four 4' bulbs.
